EARL G. WATROUS, OF CHICAGQILLINOIS.

DRINKING-EONTAIN.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed February 26, 1915. v Serial No. 10,702.

T0 all whom t may concern:

4Be it known that I, EARL G. WATRoUs, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful 1mprovements in Drinking-Fountains, of which the following is a specification.v

My invention relates to a drinking fountain prow'ded with a bubbling cup or the like and the object thereof is to provide a simple, efficient and reliable device of this kind.

My fountain is characterized more particu.

larly by a compact construction and arrangement with respect to the fixture proper and the bowl and attached housing thereof and also the bubbling cup proper and its associated parts. My fountain is also characterized by a construction and arrangement whereby the bowl and its casing as well as the bubbling cup are supported by the fixture rather than vice versa, thereby relieving said parts which are generally made of porcelain of the strain incident to the support of the fixture thereby.

Other novel and advantageous features of construction and operation will be apparent from Jthe description hereinafter given.

In the drawings, Figure l is a vertical section of a drinking fountain embodying my invention; Fig. 2 a detail view of the valve mechanism for controlling the supply to the bubbling cup showing the valve handle moved to open position; Fig. 3 a section on the line 3 3 of Fig.' 1; Fig. 4 a section on the line 4 4 of Fig. l, and Fig. 5 a vertical sectional elevation of a modified form of construction according to which a trap is provided in the waste pipe.

Referring to the particular embodiment of my, invention as shown in Figs. 1 to 4, the fountain comprises three main parts, that is the bowl 1 and its preferably integral laterally-extending casing 2 adapted to fit against the wall 3 but not attached to or supported thereby and the fixture including the supply and waste pipes and valve mechanism on which said bowl and its casing are supported, and `also the bubbling cup 4 andV associated parts which are also supported by said fxtur Referring to Fig. l, a waste pipe 5 and supply pipe 6 in concentric relationship, the supply pipe being arranged axially of the waste pipe, pass horizontally through an opening in the wall- 3 and the same are secured or supported by the wall by means of the wall flange 7 secured upon the eXteriorly screw-threaded portion of the waste pipe. The supply pipe passes through the elbow 8 which connects the horizontal waste pipe 5 and the vertical waste pipe 9. While I refer to the part 3 as a wall it will be understood that I do not limit myself to a vertical wall inasmuch as it may be any suitable support for attachment of the` Xture thereto, particul'arly the waste pipe.

At its outer end a combined valve casing and supply and waste connection 10 is mounted, preferably by screw-threading one part upon lthe other to permit of ready attachment and detachment. The supply pipe 6 is also screw-threaded into the valve casing and adapted to communicate with an inlet space or inlet chamber 11 terminating in a port 12 which is governed by the vertically movable valve 13. This valve is mounted in a sleeve 14 screw-threaded into the valve casing and having a central bore through which the stern 15 of the Vvalve passes in its reciprocating movements. This valve stem is properly packed as by means of a packing gland 16, and is surrounded at its u-pper portion bymeans of the spiral spring 17 pressing against the'under side of the valve and normally closing the port 12. The valve is operated by means of a handle of the peculiar formation shown in Figs. 1 and 2, the same consisting of a handle portion proper marked 18 and a removable head portion 19 having a central opening through which the valve stem passes. A nut 20 screws onto the lower end of the valve stem and is located within or rather'below the head of the handle. This head is provided with a curved marginal flange 21 and circular shoulder 22 which is caused to bear, by means of the pressure of the spring 17 against the lower vedges of the depending flange 23 on the sleeve 14.

It will be understood that when the handle 18 is turned in any direction, that is tilted, as shown in Fig. 2 for instance, the shoulder 22 will bear on flange 23' asa fulcrum and act as a lever between the handle and the sleeve 14 so that the head of the handle bearing downwardly against the vnut v, 20 will withdraw the valve from its seat, as shown in Fig. 2, thereby admitting the water from the chamber '11 into the chamber 24 in the valve casing. A vertical supply :tube or pipe 25 is screw-threadedintothe valve casing to communicate with the chamber 24,

iop

and on this pipe the bubbling cup et and contained parts are mounted so that the valve casing or rather the entire Xture supports the bubbling cup as well as the bowl and casing.

The bubbling cup, which is made of any suitable material such as porcelain, is cylindrical in general outline and is hollow with the exception of its extreme upper portion which is provided with a shallow cavity 26 and a series of holes 27, preferably three in number, and converging to supply a bubbling stream of water. This cup is mounted upon and secured to a casing 28 having a depending tubular extension 29 here shown as screw-threaded upon the vertical supply pipe 25. rEhe casing 28 is provided with a spider 30 having a central screw-threaded bore into which screws the fastening screw 3l extending through the top of the cup for clamping such cup and casing 23 together, a gasket 32 being preferably interposed between them.

By preference and as herein shown a governor is provided in the line of supply of water to the bubbling chamber, the same consisting of a vertical plunger 33 arranged axially of the tubular extension 29 and pipe 25 and adapted to reciprocate through a central opening of a washer 34 interposed between the inner end of the tube 25 and an interior shoulder in the extension 29. This plunger has a central bore 35 extending upwardly to ,a point midway of its length where it commuicates with side ports 36. This plunger is also provided intermediate its length at a point below said ports with a lateral flange 37 adapted to be held normally on top of the washer 34 with a yielding pressure by means of the coil spring 38. One side or ,face of the upper end of the plunger' is cut away on a taper as shown in Fig. 3, and such end is positioned within an adjustable bushing 39 which is screwthreaded in the bottom of the casing 28. It will be understood that the object of the regulator is to control the volume of the water admitted to the bubbling chamber. Under normal or adjusted conditions the water would flow through the bore or pas- 35 and through the ports 36 and thence along the inclined face of the plunger and into the bubbling chamber without causing any movement of the plunger. However, in case of too great pressure, that. is a pressure above. a predetermined amount, the plunger would be raised by the force of the water with the result that its upper end which is of increasing size from its eXtreme upper end downwardly will be raised in the bushing 39 and kthe passageway therethrough will be restricted. The volume of water thus admitted into the bubbling chamber can be regulated by screwing the bushing downwardly the said passageway will be restricted and by screwing it outwardly, that is upwardly, such passageway will be enlarged.

In order to prevent any possible rotation of the bubbling cup I prefer to employ an interlocking connection between the lower edge of the cup and a bushing' 40, which passes through an opening in the bottom of the bowl l. In the present instance this bushing which has a marginal outwardly directed flange 40 is provided with upwardly extending lugs -tl which engage corresponding recesses 2a in the inner walls of the cup, as shown in Fig. 4. 1f desired the bubbling cup may be provided with an air hole 4'* intermediate its height to supply air thereto in case the lower end of the cup should become sealed by any accumulation of the water in the bowl, thereby preventing any water hammering in the fixture.

As above stated the bowl l and its housing 2 are attached to and supported by the fixture being directly attached in the present instance to the valve casing 10. To this end the bushing l() is screw-threaded into the upper end of the valve casing thereby clamping the bottom of the bowl between the flange 40 of the bushing and the flange l0a of the valve casing, a gasket 4:2 being preferably interposed between the bowl and the flange 40a.

The water supply pipe 25 extends upwardly through the bushing 40 leaving an annular space through which the water drains directly from the bowl 1 downwardly into the chamber t3 in the valve casing, which chamber is in direct communication with the waste pipe 5.

The casing 2 is here formed as a part of the bowl l, the same inclosing the valve mechanism and the waste and supply pipes, and also supported thereby by being a part of the bowl itself.

Referring to Fig. 5 the construction is the same as in Fig. l with the exception ofthe provision of a trap in the waste pipe and with the further exception that the supply pipe does not extend through the wall yor support in concentric relationship with the waste pipe. rEhe corresponding parts are indicated by the same reference characters as in Fig. l. At its outer end the waste pipe 5 is connected with the valve casing by means of a slip joint and a coupling nut 44. At its inner end the waste pipe is secured to a trapl 45, one branch of which `communicates with such waste pipe and the other with a short pipe connection 46 secured to and supported by the wall or other support 3, the same being in the present instance in axial alinement with the pipe 5. As shown, this short pipe connection 4-6 is secured to the wall by means of the flange 7. The supply pipe 6 is also secured t0 the trap in the present instance by being vscrew-threa'ded thereinto so as to communicate with a chamber 47 therein. A short pipe 48is screwthreaded into the trap and communicates at its lower end with the chamber 47 and at its upper end as a slip-joint connection with an elbow 49 coupled thereto by the coupling nut 50 andsecur'ed to the main supply pipe 51 which passes through the wall or'other. support 3.
